2014 Chevy Impala Gets Ecotec Engine

Green Car Reports - May 25, 2013

The new 2014 Chevro­let Impala is a big five-pas­sen­ger fam­i­ly sedan, and becomes a big car with a small engine for the fuel-econ­o­my mind­ed buy­ers look­ing for bet­ter mileage.

The Impala is good, but is there a bet­ter mileage com­peti­tor out there on the road?

The new 2014 Chevro­let Impala is a big five-pas­sen­ger fam­i­ly sedan, the largest one Chevy sells.

While it was launched ear­li­er this year with a 303-horse­pow­er 3.6-liter V-6 engine, it can now also be ordered with a 196-hp, 2.5-liter four-cylin­der Ecotec engine that pro­duces 186 lb-ft of torque.

That would seem to be a small engine in a big car, but it’s in the ser­vice of—naturally—fuel econ­o­my. The four-cylin­der Impala is rat­ed at 25 mpg (21 mpg city, 31 mpg high­way) by the EPA, bet­ter than the 22-mpg com­bined rat­ing of the V-6 ver­sion.

Over that dis­tance, it returned a record­ed 25.1 mpg, which is a fig­ure you’d not have been like­ly to see from pre­vi­ous Impalas (except per­haps dur­ing high­way cruis­ing on flat roads with the cruise con­trol on).

It’s not near­ly as good as the real-world 40 mpg we got in a 2013 Toy­ota Aval­on Hybrid, but the Impala was slight­ly big­ger than Toyota’s largest sedan—and sev­er­al thou­sand dol­lars cheap­er to boot.

But under most dri­ving con­di­tions, the Impala per­formed well enough—and, dur­ing damp and inter­mit­tent­ly rainy weath­er, proved to be sur­pris­ing­ly eager to spin its inside front wheel when accel­er­at­ing out of cor­ners.

A sec­ond four-cylin­der Impala, this one fit­ted with a 2.4-liter engine and the eAs­sist mild-hybrid sys­tem already used in the Buick Lacrosse, will arrive at Chevy deal­ers before the end of the year.

That car is expect­ed to earn EPA rat­ings of 25 mpg city, 35 mpg high­way, for a like­ly com­bined rat­ing of around 28 mpg.
